FIELD

The present disclosure generally relates to the moisture control field. More particularly, the present disclosure relates to the field of moisture control in a vehicle.

BACKGROUND

In an aircraft, the outer skin is spaced from the walls and ceiling of a passenger cabin (or other compartment), and the gap is at least partially filled with an insulation layer or blanket. The insulation layer is typically formed from a waterproof material. During a flight, liquid from moist air can condense against the skin and freeze during cruise. During decent, this frozen liquid can thaw and drip back down towards the cabin. Because the insulation blanket is waterproof, the condensate can flow along the insulation blanket and drain into the bilge. However, at some locations, structures and/or supports can protrude through the insulation blanket. For example, the supports that hold monuments and bins to the crown extend from the structure at the skin, through the insulation blanket, and into the cabin. The insulation blankets come with predefined holes for the supports to extend through the blanket. The holes are lined, and there may be a gap defined between the inner surface of the hole and the support. When liquid thaws, it can drip down through the hole and into the cabin.

One previous attempt to fix this problem was to wrap the support in felt so the felt will absorb the condensate and allow the condensate to evaporate back into the air. However, the condensate may be more than the felt can absorb. Further, wrapping each support in felt can be time-consuming.

DESCRIPTION

Generally

The present disclosure generally relates to the moisture control field. More particularly, the present disclosure relates to the field of moisture control in a vehicle.

FIGS. 1-2 illustrate moisture flow in an exemplary aircraft, while FIGS. 3-6 show an exemplary moisture path close-out and thermal control system for preventing or at least minimizing moisture flow into an inner cabin portion of the aircraft, according to some aspects of the disclosure. FIG. 1 shows an aircraft 100 that includes a nose 110, wings 120, a fuselage 130, and a tail 140. FIG. 1 also illustrates a downward arrow 150 indicating the expected direction in which the force of gravity will pull objects, such as liquid water, onboard an aircraft 100 in a nominal operational profile.

FIG. 2 is a cross-sectional, schematic view of the aircraft 100 indicated by view arrows 2 in FIG. 1. FIG. 2 illustrates a portion of the aircraft fuselage 130, simplified for easier understanding of this Description. The fuselage 130 includes floor 204, ceiling 206, and aesthetic fascia walls 208 which define the cabin 202, where the ceiling 206 and/or aesthetic fascia walls 208 represent an “inner wall” of the aircraft for the purposes of this Description. Passengers in the aircraft 100 may congregate in seats 210 of the cabin 202 during flight. FIG. 2 illustrates that, inside of the fuselage 130 (e.g. in cabin 202), respiration and other sources of water cause moisture 220 to enter or form in the air in the cabin 202. For example, warm exhaled air includes moisture 220 and rises upward through luggage compartments 212. Some of this warm and moist air rises through the ceiling 206. Furthermore, some warm air continues to rise upward through an insulation layer 214 (or insulation blanket) into a space 240 between the insulation layer 214 and an outer wall 216 of the aircraft, also known as the aircraft skin. The insulation layer 214 includes an inboard surface 214 a and an outboard surface 214 b as shown in FIG. 4. Also as shown in FIG. 4, an aperture 215 extends through the insulation layer 214, including through the inboard surface 214 a and the outboard surface 214 b.

Referring again to FIG. 2, as the skin 216 is cooled by the outside air at high altitude during flight, the temperature of the skin 216 eventually decreases to a temperature below the freezing temperature of water. This cooling causes moisture 220 (e.g., water) to condense out of the air in the space 240 and freeze onto the inner surface of the skin 216 as ice 218. As the aircraft changes to a lower altitude and/or commences descent for landing and the temperature increases, the ice 218 begins to melt causing water droplets 230 to travel through the space 240 towards the bottom 250 of the fuselage 130, drawn by gravitational force 150. Some water droplets 230 enter gaps in the insulation layer 214, particularly where support beams 222 pass through apertures 215 within the insulation layer 214, and drip into the cabin 202, sometimes on passengers. The size of the space 240 has been exaggerated somewhat in FIG. 2 in order to more clearly show the details of the structure. Support beams 222 are often used for attaching aircraft components 224 such as luggage compartments 212, the ceiling 206, ducting, equipment, and racks, as examples. For simplicity, common aircraft load bearing components such as stringers and/or frame members are not shown, but it should be understood that in some aspects, support beams 222 attach various aircraft components to stringers and/or frame members, and not directly to the outer wall 216 of the aircraft 100.

FIG. 3 is an exemplary block diagram of a moisture path close-out and thermal control system 300 (also referred to as a “moisture control system” or a “moisture control assembly”), in an aspect of the disclosure. In some aspects of the disclosure, a moisture path close-out structure 302 is provided to the system 300 at a location vulnerable to moisture leakage into the cabin 202, for example at the juncture between a support beam 222 and the insulation layer 214 where typically there is a small gap. An umbrella-shaped structure 402, shown and described in more detail with respect to FIGS. 4-5, is provided to the system 300 as the moisture path close-out structure 302, in an aspect of the disclosure. It should be understood that the umbrella-shaped structure 402 is by way of example only, and that other functionally equivalent structures could be used to prevent moisture from seeping into the junction between the insulation layer 214 and the support beam 222. In an aspect of the disclosure, the moisture path close-out structure is generally umbrella shaped at the top, but has a different shape (for example ovoid, square, irregular, rectangular, multi-sided) at the bottom, depending on the available surface area near the aperture 215 sought to be closed. The moisture path close-out structure 302 includes an opening, such as an opening 414 shown in FIG. 4. The opening substantially aligns with the aperture 215 through the insulation layer 214 and receives at least a portion of the support beam 222 therethrough.

In an aspect of the disclosure, the moisture path close-out structure 302 also substantially, or even prevents, airflow between the cabin 202 and the space 240 through the junction between the insulation layer 214 and the support beam 222. For example, the moisture path close-out structure 302 is constructed of an air impermeable material, such as existing insulation blanket cover materials (such as BMS8-380 Type 4 (Halar)—˜1 perm, BMS8-380 Type 3 (MPEEK)—˜0.5 perm, BMS8-380 Type 2 (PEKK)—˜4 perm) and/or similar low permeable lightweight fabric. In an aspect, any material that is waterproof and can pass flammability, smoke and toxicity testing could be used. By blocking the airflow from the cabin 202, the moisture 220 from the cabin 202 is prevented from entering the space 240 and condensing and freezing on the skin 216 in the first place.

A coupling mechanism 304 is used to couple the moisture path close-out structure 302 to the support beam 222 such that moisture flowing down the support beam 222 cannot penetrate the coupling and must flow from the support beam 222 onto the moisture path close-out structure 302 and towards the insulation layer 214 (shown and described in more detail with respect to FIG. 4), where the moisture will eventually end up at the bottom 250 of the aircraft fuselage 130. In some aspects of the disclosure, the coupling mechanism 304 is an integral part of the support beam 222, optionally resulting from the support beam 222 being manufactured with the coupling mechanism 304 in the same manufacturing process. In some aspects, the coupling mechanism 304 is separate from the support beam 222 and is attached at some point prior to or as part of moisture path close-out and thermal control system installation. Such a configuration is useful for retro-fitting support beams which have already been manufactured/installed without the coupling mechanism 304, for example.

In some aspects, the coupling mechanism 304 couples the moisture close-out structure 302 to the support beam 222 using pressure/compression, adhesive, fasteners, tabs, screws and/or nails, stitching, wrapping, hook and pile fastener, zip-tie, threading (like a screw), an external pressure exerting device (such as described with respect to FIG. 4), and/or other device and/or method functionally sufficient to secure the moisture close-out structure 302 to the support beam 222 in a moisture impermeable manner.

In some aspects of the disclosure and as described in more detail below, a support beam 306, such as the support beam 222, is provided to system 300 which is configured to assist with temperature control, which has an effect on moisture control.

Umbrella-Shaped Moisture Path Close-Out Aspect

FIG. 4 is an exemplary side, partial cross-sectional view of a portion of a moisture path close-out and thermal control system 300 using an umbrella-shaped moisture close-out structure 302 as the moisture close-out structure 302. The umbrella-shaped structure 402 includes an opening 414. The opening 414 substantially aligns with the aperture 215 through the insulation layer 214 and receives at least a portion of the support beam 222 therethrough. In an aspect, the support beam 222 passes through the aperture 215 in the insulation layer 214 and the opening 414 in the umbrella-shaped structure 402 and connects on an outboard side of the system 300 (with respect to the insulation layer 214) and on an inboard side (with respect to the insulation layer 214) to a portion of the inner wall of the aircraft 100 and/or aircraft components 224. In an aspect of the disclosure, the coupling mechanism 304 includes a frusto-conical shaped flange 404 through which passes the support beam 222 and/or which is attached or integral to the support beam 222. It should be noted that in this example, the flange 404 is frusto-conical in shape to match the general shape of the umbrella-shaped structure 402; in other examples, where the moisture path close-out structure 302 is another shape (i.e. not conical), the coupling mechanism 304 might be shaped differently. The flange 404 is configured to be reversibly attached to the support beam 222, in some aspects.

The umbrella-shaped structure 402 is positioned with respect to the flange 404 such that droplets 230 flow down the support beam 222, flow over the flange 404 and over, but not through, the coupling between the flange 404 and the umbrella-shaped structure 402 and onward onto the insulation layer 214, where it continues around on the water-proof insulation layer 214 to the bottom 250 of the fuselage 130 (due to gravitational force 150). In an aspect of the disclosure, this means that the upper end of the umbrella-shaped structure 402 is positioned within a flange cavity 408 of the flange 404 and on the side of the insulation layer 214, such that at least a portion of the flange 404 overlays the top of umbrella-shaped structure 402.

In an aspect, the flange 404 is located on the support beam 222 such that when the umbrella-shaped structure 402 is coupled to it, the upper end of the umbrella-shaped structure 402 is higher than the insulation layer 214, providing a downward slope to the umbrella-shaped structure 402 from the support beam 222 towards the insulation layer 214. In an aspect, the distance between the flange 404 and the insulation layer 214 depends on the insulation blanket used and the angle of the support beam 222. In an aspect, the material of the umbrella-shaped structure 402 is configured to be slack enough to allow for movement of the support beam 222 without imparting a load on the material or insulation layer 214. In some aspects, the coupling between the umbrella-shaped structure 402 and the flange 404 pulls the umbrella-shaped structure 402 in an outboard direction and away from the insulation layer 214 to create a slope.

In an aspect of the disclosure, a plug 406 is also placed around the support beam 222, but shaped to fit within the flange cavity 408 and press the umbrella-shaped structure into the flange 404, thereby securing the umbrella-shaped structure 402 between the flange 404 and the plug 406. In some aspects, the umbrella-shaped structure 402 is secured to the plug 406 additionally or alternatively to being secured to the flange 404. In some aspects, the plug 406 is compressible (and larger in diameter than the flange cavity 408) such that when the plug 406 is pushed up into the flange cavity 408 of the flange 404, the plug 406 compresses and secures the umbrella-shaped structure 402 via a compression fit and/or friction fit of the plug 406 within the flange 404. In some aspects, the umbrella-shaped structure 402 is secured to the plug 406 and/or the plug 406 is secured within the flange cavity 408 using adhesive, fasteners, tabs, screws and/or nails, stitching, wrapping, hook and pile fastener, zip-tie, threading (like a screw), an external pressure exerting device (such as described with respect to FIG. 4), and/or other device and/or method functionally sufficient to secure in a moisture impermeable manner. The umbrella-shaped structure 402 is reversibly attached to the support beam 222, in some aspects.

In an aspect, the volume 412 between the umbrella-shaped structure 402 and the insulation layer 214 is filled with a material/filler 410 (shown partially in FIG. 4), for example, to prevent condensation from collecting in the volume 412 and/or to assist with mechanically holding the plug 406 in the flange cavity 408 by filling the volume 412 to an extent that the plug 406 is mechanically pushed into the flange cavity 408.

It should be understood that the view of FIG. 4 is of a single support beam 222 with a moisture path close-out and/or thermal control system 300 in place, and that similar configurations are optionally repeated at other support beams in the aircraft 100 where the system 300 would be of benefit for reducing precipitation of liquid moisture in the cabin 202. In some aspects, the aircraft 100 is configured with systems 300 on some or all support beams, which are located at or above where the width of the fuselage 130 is at its greatest from the cross-sectional perspective of FIG. 2.

FIG. 5 is a top view (from an outboard perspective looking inboard) of a portion of a moisture path close-out and thermal control system 300, including an umbrella-shaped structure 402 located within a flange 404. In an aspect, both the umbrella-shaped structure 402 and the flange 404 are positioned around the support beam 222. In some aspects of the disclosure, the umbrella-shaped structure 402 is fastened to the insulation layer 214 at least with a first seam 502 and optionally, with one or more additional seams 504 to prevent moisture from penetrating the junction between the umbrella-shaped structure 402 and the insulation layer 214. In an aspect of the disclosure, the seams 502, 504 are joined in a water impermeable fashion using an adhesive, stitching, and/or any of the other securing methods described herein and/or available in the art. In an aspect, and as shown in FIG. 5, the material of the umbrella-shaped structure 402 does not need to completely cover the surface of the insulation layer 214 because the insulation layer 214 is already typically waterproof and the extra material would add unnecessary weight. In an aspect, the insulation layer 214 would include the umbrella-shaped structure 402 as a patch coupled over a predefined hole/aperture 215 through the insulation layer 214.

An access seam 506 is optionally provided to the umbrella-shaped structure 402, for example to allow access through the system 300, either from inboard going outboard, or vice versa, for example for access during installation of the system 300. In an aspect, the access seam 506 is water/moisture impermeable when closed. In some aspects, the access seam is water and vapor proof, using for example a water and vapor impermeable zipper and/or a hook and loop seam.

It should be understood that while the support beam 222 is shown as being circular in shape, the support beam 222 could be any shape and where the moisture path close-out structure 302 and the coupling mechanism 304 are configured to match that shape in order to effectively render the junction between the support beam 222 and the insulation layer 214 water impermeable, particularly from the outboard towards inboard direction.

Temperature Control Support Beam Aspect

In some aspects, temperature control is utilized to maintain the support beam 222 above the dew point, at least in areas inboard of the moisture path close-out structure 302 and/or the insulation layer 214, to minimize condensation. FIG. 6 is a side view of a support beam 222 with an insulating layer 602 positioned between the support beam 222 and the outer wall 216 (or wherever outboard of the insulation layer 214 the support beam 222 attaches) of the aircraft 100, in an aspect of the disclosure. In an aspect, the insulating layer 602 is used to control the temperature of the support beam 222 by limiting the direct heat transfer path between the cold outer wall 216 (at altitude) and the support beam 222, ideally reducing condensation of moisture 220 present in the space 240. Alternatively or additionally, an insulating layer is similarly positioned on the inboard side of the support beam facing the inner wall (or wherever inboard of the insulation layer 214 the support beam 222 attaches). In an aspect, the insulating layer 602 is secured to the outer wall 216 using any of the methods described herein and/or known to those skilled in the art.

In an aspect, the support beam 222 is insulated over its entire length, for example, being coated with an insulating material and/or being wrapped in a layer of insulation and/or being constructed of a material which has a lower thermal conductivity relative to conventional aircraft construction materials.

Method of Assembly Aspect

FIG. 7 is a flowchart of a method (700) for assembling a moisture path close-out and thermal control system 300. In an aspect, the support beam 222 is inserted (702) through an aperture 215 defined through the insulation layer 214 and an opening defined through the moisture path close-out structure 302. In some aspects, the moisture path close-out structure 302 is previously coupled to the insulation layer 214, for example, during manufacture of the insulation layer 214. The moisture path close-out structure 302 is coupled (704) to the support beam 222 by the coupling mechanism 304 such that a portion of the moisture path close-out structure 302 is pulled (706) away from the insulation layer 214 to impart a slope to the moisture path close-out structure 302 directing liquid moisture flow down from the support beam 222 and towards the insulation layer 214. In an aspect, the coupling (704) is achieved by securing the moisture path close-out structure 302 between the flange 404 and the plug 406. In an aspect, the moisture path close-out structure 302 is the umbrella-shaped structure 402 described elsewhere herein. In an aspect, the coupling mechanism 304 is attached (708) to the support beam 222 prior to coupling (704) the moisture path close-out structure 302 to the support beam 222, for example, where the support beam 222 is being retro-fitted to accept the moisture path close-out and thermal control system 300.
